Bathroom exhaust fans play a critical role in protecting your health and maintaining the indoor air quality of the bathroom space and the whole home. Why do I need a bathroom fan? The primary purpose of a bathroom exhaust fan is to remove excess moisture out of the bathroom. During a bath or shower humidity levels rise significantly. Excessive moisture can create the perfect breeding ground for mold, mildew and bacterium that can negatively impact health. These spores can grow rapidly and can be hard to eliminate. Long-term excess moisture and humidity can crack and peel paint, breakdown cabinet finishes, rusting of hardware and fixtures, and acute damage to tile, grout and flooring. Without control, it can even cause deterioration of joists and framing of the bathroom. Not just and odor eliminator One of the most appreciated benefits of a bathroom exhaust fan is for odor control. If an unpleasant odor occurs, it can easily be vented outdoors with a bathroom fan. Leaving a pleasing atmosphere for the next person who enters the bathroom. Bathrooms are commonly cleaned with heavy-duty chemicals which have strong fumes and can cause a variety of health issues when inhaled. Especially for small children, the elderly, or those with respiratory conditions. A bathroom fan helps to exhaust these chemical fumes to the outdoors.
Additionally, if a bathroom is experiencing mold problem, the fan will help to remove buildup of spores in the air. This in turn helps slow down the growth rate of the mold.
If your bathroom doesn’t have a fan and smells musty, it’s likely you need to install a bathroom exhaust fan. How does a Bathroom Fan Work?

A fan should not be exhausted into the attic space. This is simply shifting the moisture from one room to another. Bathroom fans will vary by power, are rated in CFM (cubic feet per minute) which is a measurement of how much air the fan can draw from the room over a period of time.
